Wu Ming waited for a while and then went to have dinner.
Under the night sky.
He held Wan Siyu in his arms and they fell into a deep sleep after a fierce battle.
Ring ring ring!
At five o 'clock the next morning, Wu Ming was woken up by the alarm clock. Sleepy, he suddenly remembered something.
"Right!"
"The first batch of black-patterned bricks is coming out."
Wu Ming got up at once and went to the door.
He turned off the electricity and cooled it down.
Wu Ming put on the third-generation dragon-scale armor. He turned on the hot oven and took out more than a dozen black-patterned bricks that would make a clanking sound when rubbed against each other.
Before firing, the black-patterned bricks were 10 centimeters long, 5 centimeters wide, and 3 centimeters thick. At the moment, they had expanded to 20 centimeters long, 10 centimeters wide, and 6 centimeters thick.
They were full of holes.
They looked like a piece of black bread or a volcanic rock that had been polished into a square shape.
Wu Ming took out a steel kitchen knife and hacked at the brick.
Clang!
The kitchen knife curled up but the black-patterned brick remained intact.
Su Ping took out a super-alloy dagger and stabbed at the black-patterned brick. The tip of the super-alloy dagger broke off. As for the black-patterned brick, there was finally a small crack.
But the damage wasn't severe.
"It worked!"
Wu Ming was delighted.
A black-patterned brick that could withstand the sudden stab of the super-alloy dagger would be in great demand in the future.
With that said, Su Ping took out the super-alloy dagger and stabbed at the floor. Soon, the dagger pierced through the brick that was about 10 centimeters thick.
On the other hand, the black-patterned brick was only scratched on the surface. It was hard to break it open.
"Let's use a regular brick as the core and then lay one or two layers of black-patterned bricks on the surface. The strength should be good enough."
Wu Ming said.
At the moment, the black-patterned bricks weren't being produced in large quantities.
To achieve mass production, Su Ping would have to plant more pets of the plant family like the Exploding Coconut Tree so that they could obtain the Magic Fruit, which was a Class F talent.
When the number of fruit trees increased, the black-patterned bricks could be mass produced.
"It won't be too late to start the mass production plan after the mayor and the others are here to verify the practicality of the black-patterned bricks in person."
Wu Ming went back to the pet store.
It was only half past five and he was about to go to bed.
However, Wu Ming slapped his head and thought of a flaw.
The black-patterned bricks were very strong, but if they were connected piece by piece with cement mortar, the strength was still not enough.
After the ordinary cement mortar was solidified, the ferocious beasts could tear it apart with their claws. Then, they could dismantle the black-patterned bricks one by one to break through the defense.
"We have to get a binder to replace the cement mortar."
Wu Ming muttered.
He sat on the sofa and entered the System Store with his consciousness. Soon, he found an F-grade evolutionary food formula.
[Super Sticky Food: Rank F]
【Recipe: F-Rank Vicious Beast Inner Core x120 g, Viscous Mud x99 g … Molitona Berry x56 g, and seven other medicinal ingredients. Evolution Points x8】
[Effect: Pets of the plant family that have taken this food will be able to bear fruits that contain super viscous liquid. The liquid will be completely solidified after being exposed to the air for one hour. The fruit will have super adhesive properties and its strength is comparable to that of super alloy steel.]
"This is good!"
Since Wan Siyu was still in bed, Wu Ming had to do it himself. He searched in the System Store and the pet store, gathered a set of raw materials, and began to mix.
Fifteen minutes later.
Wu Ming walked to the Exploding Coconut Tree with an evolutionary food that looked like a golden jelly.
"Eat it!"
The exploding coconut tree immediately extended a straw and sucked up the golden jelly with a "slurp" sound.
Then, the tree trembled.
Below the original fifteen coconuts, there were five slightly smaller greenish-white coconuts.
Those were the super viscous fruits.
"Give me a super viscous fruit … Don't make it into an Exploding Coconut Tree!" Wu Ming reached out his hands.
The tree trembled. A bluish-white, super viscous fruit fell off and was caught by Wu Ming.
He walked to the table, cut open the fruit, and filled a large glass with 2,000 milliliters of super viscous liquid.
Wu Ming put on gloves and scooped up some super viscous liquid with a spoon. He found that the super viscous liquid had a high viscosity, similar to cement mortar. It was suitable for building materials.
"It's time to start moving bricks."
Wu Ming laughed at himself.
He used two spoons of super viscous liquid to glue the two black-patterned bricks together and put them on the table.
The super viscous liquid would only solidify after it was exposed to the air for an hour and reacted with oxygen.
By then, the strength and viscosity of the bricks would reach the maximum.
Wu Ming put a lid on the remaining super viscous liquid and filled it with nitrogen to prevent it from reacting.
This way, the super viscous liquid could be stored for a long time.
An hour later.
Wu Ming finished washing up and had breakfast. He found that the two black-patterned bricks had been glued together perfectly.
He tried to pry them apart but they wouldn't come apart.
"Good heavens. These two things will definitely become the hottest items!" Wu Ming looked around. "When I renovate the pet store, I will put up black-patterned bricks everywhere."
"Brother Wu, why are you up so early?"
At this moment, Wan Siyu had woken up as well.
"I'm up to move bricks," Wu Ming said with a smile, "Wash up and have breakfast. I need to catch up on my sleep."
"Okay." Wan Siyu nodded.
In the blink of an eye, it was noon.
Boom!
A fleet of luxury cars drove onto Nanwen Street and parked dozens of meters away from the pet store.
Twenty-one city lords got out of their cars at the same time.
"Brother Wu, the city lords are here."
Wan Siyu was startled to see the dozens of city lords waiting outside. Back then, she was just a shop assistant. Instinctively, she felt fear when she saw the city lords.
But on second thought, she was Wu Ming's shop assistant and she had become a beast tamer. Her status was no longer what it used to be. Soon, she calmed down.
"Okay, I see."
Five minutes later, Wu Ming went downstairs.
"These are black-patterned bricks," Wu Ming added, "This is super viscous liquid, used to glue the black-patterned bricks together.
Both of these materials are super alloy steel and are suitable for the construction of fortifications. "
"Are they really as strong as super alloy steel?"
"Sir Lord, can we give it a try?"
The city lords asked one after another.
"Let's try!" Wu Ming didn't turn them down.
Jialan City's City Lord was the first to take out a super-alloy steel dagger and fiercely stab at the black-patterned brick. As a result, the dagger broke and the black-patterned brick was only scratched on the surface.
"Hiss!"
"Once this kind of building material is released, it will be a popular product in the entire Huaxia!"
"Wait, how much does it cost?"
"That's right. The cost of production is very important. This is the key to whether the black-patterned bricks and super viscous liquid will sell well."
"If it's too expensive, I'm afraid we won't be able to sell it."
"Some cities have installed a layer of super alloy steel armor on the surface of the city walls. The defense is not bad, but the cost is too high. If the black-patterned bricks are cheaper than super alloy steel, then the city lord will definitely dominate the market."
The city lords all looked at Wu Ming.
In the seat.
Wu Ming was looking at the tablet and found the cost of super alloy steel. He said, "In the case of the same volume, the cost of black-patterned bricks is less than one percent of super alloy steel."
"Hiss!"
Hearing this, the 21 City Lords present collectively sucked in a breath of cold air. Their faces were full of shock.
They knew that Garan Castle was going to be rich!
